No matter whether we use the method of Bone Weight Copy or make Parent, there will always needed to fix some BUG'S be hand craft, before a model is correct poseable. $AtlantiB$ it has shown here , how to work with Weight Paint to fix the errors.

The surface must be connected to the bone, that they should move. Each vertex (vertex) of the grid (wire frame) must connected with exactly 4 bones to works correct with XNALara. If this is not necessary (as with the lower teeth), then my programs automatical connect this vertex with the 'root ground' bone.
The bone weight indicates how exactly the surface follows (with what strength) the bone.
A value of 0 means: Do not move with this bone.
A value of 1 means: Exact (exact) follow the bone move.
The sum of all 4 values for each point on the surface must be 1 in result. This can be done by invoke the 'normalize' menu item inside Blender. [IMG]http://i39.************/5k25g8_tn.jpg[/IMG]

2. In Blender, we use the 'Weight Paint' mode. Select the Sub-Mode 'Blur'. The values for 'Weight' and 'opacity', we set to 1 Paint with the brush over the bad place, thren the values of neighboring vertices are copy to this place.

3. Each lips bone is tested. Some places move with the wrong bone:
The lower lip moving here with the bone 'head lip upper left. "
We change f from 'Blur' to 'Sub' Tool and decrease the connection to the upper lip. Simply paint over the blemish.

1. The lower teeth should only move with the mandible (jaw head). The necessary technology was shown at the AOD-glasses .
Switch from 'Weight Paint' mode to the 'Edit' mode. Select All vertices and delete the connection to all the bones (except for 'head-jaw).

English:
Maybe you recognized, that some mods are missing "Look At" points in XNALara. This is caused by the mesh-names. Right behind the info for shine, bump1 and bump2 strength you can add (separated by another "_" the standard spearator for values in the mesh names) the focus points. the first value is the name of the focus, followed by the bone name that should be assosiated to this focus.
5_mesh004_0.1_0_0_body lower_pelvis

"Body lower" is the focus name, "Pelvis" the assosiated bone. Multiple bones are possible as well:
